iPhoto ‘11: Magnification Shortcuts

If you need to zoom in on an image you're editing in iPhoto, there are a couple of ways to go about it. The most obvious method is to use the Zoom slider at the bottom of the window coupled with the small Navigation panel to move around in your magnified image.

I find, though, that it's much easier to use keyboard shortcuts. To do this, double-click on an image from your library to view it solo first, then place your cursor on the part of the picture that you'd like to magnify.
